nice photo,

i believe he's carring from the left, a S&W in .32 rinfire,i see no loading lever, a .31 colt police, and a .44 colt army. his shoulder weapon appears to be a m1842 smoothbore, i do not see evidence of a rear sight.all of these weapons are undoubtly photograpers props. just a guess on my part though,Pvt.S.N Renner 1stUSSSCoG.
